电法和触探在呼伦贝尔草原盐渍土路段的应用研究

Application research based on electric method and penetration in saline soil of Hulunbuir grassland

呼伦贝尔草原分布有大面积的盐渍土区,属不良地质现象。该地区盐渍土属软弱土层,其厚度分布不均匀,主要成分为泥炭质土、软粘土等。为了研究呼伦贝尔草原盐渍土的分布位置和厚度,以阿拉坦额莫勒至阿日哈沙特口岸公路项目K71路段为例,结合现场钻探、高密度电法和PANDA2可变能量轻型触探仪等地质勘察方法研究该盐渍土路段,从而可以得知盐渍土路段的地层分布情况和不同深度的土体强度。

Saline soil is a bad geological phenomenon,widely distributed in the Hulunbuir grassland.The saline soil in this area is a soft soil layer with uneven thickness distribution.The main components are peat soil and soft clay.In order to study the distribution position and thickness of the saline soil in Hulunbuir grassland,this paper takes the K71 section of the road from Alatan Moller to Azha Hasat Port as an example,combined with on-site drilling,high-density electrical exploration and PANDA2 variable energy light probe.The geological survey method is used to study the saline soil section,so that the distribution of the saline soil section and the soil strength at different depths can be known.
